I like them because they are less complicated and tend to lead to a cleaner finish IMO. But there's the side of me that knows that the connections aren't perfect and are prone to corrosion problems. What are you guys using, from r how long and why did you choose what you chose?

Common grounds are, battery to motor, battery to fender, and motor to firewall.
These are important and are something that should not be skimped on.

Just clean the common grounds every few years, and coat them with conductive grease. I've never had a corrosion issue.

I use this but there are much cheaper options: https://smile.amazon.com/gp/product/B003F8A9VO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
That grease is something I keep on hand for other projects anyway.

How critical is the using sand paper to work it in like the intstructions say on the tube?
I usually just clean the connections up really well, coat the piece and assemble.

I don't use that exact brand, but what you do is just fine.

For a little extra belt and suspenders, I ran 10ga wire between ground locations and added a few while I was at it (interior was out and I had the materials on-hand). A single black 10ga wire, it takes looking for with all of the brightly colored power wires and circuit breakers. I use Liquid Electrical Tape

i raised the question because i ran a second fuse box for accessories and these accessories need grounds and so do my relays. the engine bay is starting to get cluttered to the point that i dont like looking at it.

Depending on your current load if you have the chassis grounded to the motor and battery well enough you should be able to ground whatever, wherever you need to to the chassis.

Every ground I wire goes back to the battery.

I won't be the one with future ground issues.

Upgrade your "Big three" grounds - battery to body, battery to engine block, and engine block to body- and be done with it.
You don't have to use the factory attachment points, either.

My accessory grounds (if critical, like audio system) all go to a copper plate (procured years ago when I was a car audio installer, before copper went stupid on the commodities market) with a short jumper to the battery negative. Otherwise I'm running 00 welding cable soldered and heatshrunk to replace the Big Three grounds, with the attachment points being cleaned down to bare metal, installed with a star washer, and then painted over. On further thought, I am really liking the use of liquid electrical tape instead of paint. I overlooked that product since it's always seemed like a "flunkie tool" for idiots that don't know how to use electrical tape (seriously, after spending a few years doing high-end installs and reworks of customer supplied equipment, you see some stupid crap). Using it to paint over the proper grounding points on the body is a brilliant use that I'm sorry to say never occurred to me.
